Atherton & District Amateur Photographic Society

Can anyone recommend somewhere that does canvas prints?
I have a family portrait, I think I want it around A1.
There is a lot of colour, this is not a high key picture, so the print quality is a high priority.

I don't mind if it's local or on the world wide wonderweb.
Speedy delivery by Mothers Day would be nice........(someone could have reminded me ).

I've used these in the past - found them to be very good...

Thanks Andrew, they have a lot of options on there.
I think I'm going to have to use these, due to time constraints, anyone any experience?
